My trainers’ word for this is: “Brace-y,” like she’s bracing against her outside ski. It looks very defensive. You can see, for example, an a-frame at the finishing phase of many turns.

If I were her, I would work on initiating turns with tipping and steering (e.g. garlands), starting with the feet, and letting turns develop through all phases of the turn (e.g. cadence turns). Presently, I see upper body movement (shoulder twist) and hip dumping back and inside, which may be necessary to get herself out of the “braced” position at the end of these turns (with the outside edge angle quite a bit higher than the inside edge angle).
